What is 12+5x=2x-9 step by step

x = - 7

How to:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation

5°x - (2°x-9) = 0

Pull out like factors:

21 + 3x = 3 • (x + 7)

Equations which are never true: Solve 3 = 0

Solving a Single Variable Equation:

Solve : x+7 = 0

Subtract 7 from both sides of the equation : x = - 7
